Blade-Chaco Women's Tulip Sandal, also known as shark-tooth studs, are designed to promote better traction, reduced slippage and greater kicking stability.^{WENBOH Ms. Martin Boots Thick-Drilled Buckle Square Head Non-Slip High-Heeled Short Large Size Women's Shoes,Silver By Mail Sahran Ring}These studs promote higher friction torque^{Landau Essentials Women's Cardigan Warm-up Scrub Jacket}and improves performance, especially in runs with change of direction,^{Drive Medical 18141 Oxygen Cylinder Racks 1 per Case,BP 1461-720-10-S}compared with round-Chaco Women's Tulip Sandal. On the other hand, runs with fast changes of direction associated with high boot traction can increase the mechanical overload, especially to the knee joint, causing a potential increase in the risk of anterior cruciate ligament (ACL) injuries.^{NightyNite® Majestic"Easy Change" Cot Mattress 120 x 60 10cm with Easy Zip on Off Spare Cover - One for The Wash!,Samsonite Unisex Adult's Suitcase Blue Size: One Size-Clarks Women's Chartli Fame Pump}Besides that, the greater traction promoted by the penetration of the studs in the lawn can promote greater peaks of pressure on the sole of the feet,^{5.11 Tactical Women's Taclite PDU Class B Short Sleeve Shirt}as well as greater incidence of metatarsal stress injuries.^{EASTPAK Out Of Office Backpack - 27 L}

Subsequently, the duplicates were removed and the abstracts were read to identify those who met the inclusion criteria: articles written in English, original studies,£178.42£178.42, studies related to the influence of boot studs. After exclusion of articles that did not meet the inclusion criteria, the remaining articles were selected to be fully read and those that did not investigate overload due to the use of blade-£185.86£185.86. The following information was selected in each article included: author, year of publication, methods, footwear model used, evaluation instruments, dependent variables and results. To minimize the chances of not finding all the articles that fit the scope of this study, the references of selected articles were also checked.
